Then I've started a vncserver with the vncserver script and used my browser as a viewer at machine:5801. I typed machine:5801/vnc_test in a new browser window. The Tigervncviewer viewed my current desktop, but I want it to start a new desktop session.

Can anybody help me change the index.vnc file to start a new session? Any other sollutions to start a vncserver form a browser are more than welcome!
